Closed loop resonator using fuzzy controller

摘要

A closed loop regulator includes a fuzzy logic control unit (4) that generates a control parameter (a) to produce a connection that is based upon the values (e1, e2) that represent a proportional term (e2) and a derivative term (e1). The range of the inputs (e1, e2) are considered by seven ranges defined in linguistic terms relation to the null point; such as negative small, negative medium, negative large, etc. The variation with each range is defined by overlapping membership functions. Specification outputs are defined for each range. The fuzzy action for the PD control is summed with the integral action (5).
